IMPROVEMENT IN LUBRICATORS FOR CAR-AXLES.

Specification forming part of Letters Patent No. 130,470, dated August13, 1872.

Specification describing means for LubricatingOar-Axle Journals,invented by GEORGE A. BRANNAN, of Baltimore city, in the county ofBaltimore and State of Maryland.

The invention consists in lubricating the journal of a car-axle by meansof two feltcovered rolls, one of which has said felt in arc-flaps whichdip into the oil-reservoir, and receives its motion through the mediumof spur-gears from the upper felt-covered roll which is driven byfrictional contact with the car-axle journal.

Figure 1 is a longitudinal section of journalbox, and Figs. 2 and 3,transverse sections.

A represents the journal-box, and B the journal. 0 is a roll coveredwith felt, while D is another roll providedwith two or more absorbentarc-flaps, of felt or analogous material. c d are spur-wheels whichconnect and enable the rolls to work together. E is the oil-vessel, andF the roller-frame supported upon springs f,which are fastened insockets f These sockets and the upright bearings rest upon thecross-pieces f f. The

frame is also made to fit snugly up to the journals against the annularprojection b.

The mode of operation is as follows: As the car-axle revolves thefelt-r0110, being pressed into contact therewith by springs f, isrotated by friction. By means of the spur-wheels c d the roll D isturned and caused. to dip its flaps in the oil of box IE. As therotation continues the flaps on roll D oil the felt-sun face of roll 0,which in turn lubricates the Witnesses:
